Analysis of Ink Formulations Case Studies

Ink formulation research and development

Ink formulations require novel approaches in order to optimise product performance with product chemistry. Characterisation and analytical science are crucial aspects to achieving this balance. New ink products must meet demanding specifications for processability and product performance on printing substrates in order to be competitive.

New ink formulation project examples:

Ink formulations can suffer from transient forms of instability, due to gas evolution. Intertek Gas Chromatography - (GC) analysis to identify the trace quantities of evolved gas and quantify the effect. This enables a client to assess the risk in use, and proceed to the next stage of the project.

A complex new dye was developed with a labile structure, and needed clarification to satisfy product launch criteria. Intertek developed the structural understanding and methodology using a combination of spectroscopies, including High Resolution Nuclear Magnetic Resonance Spectroscopy (NMR), Matrix-assisted laser desorption/ionization Time-of-Flight Mass Spectrometry (MALDI-TOF), Liquid Chromatography - Mass Spectrometry (LC-MS) and molecular dynamics modelling.

Unusual and undesirable optical effects were observed for an ink after application to the substrate. Light microscopy was used, and understanding of colour space to develop a methodology for quantification of the effect was accomplished. Fundamental studies using advanced Scanning Electron Microscopy (SEM) facilities and Atomic Force Micropscopy (AFM) were also conducted to relate effects to other molecular physico-chemical parameters.

All of these ink formulation research studies were carried out under considerable time pressure, supporting development programmes with tight delivery deadlines. Intertek is ready to assist your ink and dye formulation project with the same professional analytical support.
